ABSTRACT
Wireless communication has been successfully used in a variety of mobile applications, including those with real-time requirements. In such systems, timing guarantees are normally obtained by using a TDMA-based Medium Access Control (MAC) protocol, relying in a coordinator node in charge of time-slots allocation. However, certain applications cannot make use of such coordinator because it simply does not exist, normally due to restrictions in the operation environment. To solve this problem we present in this paper a MAC protocol that operates without a central coordinator, with minimum global information, and with no previous assignments of roles to nodes nor resource reservations. Our proposed Hybrid Contention/TDMA-based (HCT) MAC is specially designed to work with ad-hoc wireless networks organized in clusters, providing timely bounded communications both inside and outside the clusters. This paper presents a detailed description of the resource reservation procedure of HCT, including an analytical analysis of its expected performance.

A hybrid reservation/contention-based MAC for video streaming over wireless networks
To reserve or not for bursty video traffic over wireless access networks has been a long-debated issue. For uplink transmissions in infrastructure-based wireless networks and peer-to-peer transmissions in mesh or ad-hoc networks, reservation can ensure ...
